National V vehicles can still be driven after the implementation of National VI. The differences between National VI and National V are: 1. Different carbon monoxide emissions: National V carbon monoxide emission is 1000 milligrams; National VI carbon monoxide emission is 700 milligrams. 2. Different emission limits: The emission limit for National V is 0.0045 grams per kilometer; the emission limit for National VI is 0.25 grams per kilometer. 3. Different names: National V is officially called the National Fifth Stage Motor Vehicle Pollutant Emission Standard; National VI is officially called the National Sixth Stage Motor Vehicle Pollutant Emission Standard. Both National V and National VI regulate the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulates, and carbon smoke emitted from vehicle exhaust.
